tion in cylindrical tanks-of glass newcommon'ly used in and;'const1ti itmgpart o f gasoe,

line-dispensing apparatus. The problem is to place'upo'n the tank walls legible marks of graduation which shallibg t h i b and accurately placed. 1

The objections to forming'these marks in thesubstanceofthe glass while the'cylinder is -being formed are "(apart from the in-. creased difliculty and cost of production) that at best such marks cannot be made easily legible, nor can they be placedwith sufiicient accuracy to meet the conditions. The objections to painting the marks upon [the finished cylinder are that it is diflicult to'find a sufiiciently adherent and durable paint. If applied exteriorly the paint has to endure exposure to weather and if applied interiorly it has to endure immersion in gasoline and in either case durability is a problem. v

' In the accompanying drawings Fig. I is a fragmentary View in elevation andFig. II a view in horizontal section of the glass cylinder which constitutes the side wall of the measuring chamber of gasoline-dispensing apparatus of familiar form,hav'ing my invention applied toit. Figs. III and IV are views in detail, and to larger scale,

- showing in plan and in el'evation the interengagement of the ends of the band in which my invention centers. Fig. V is a view in elevation and also to larger scale, showing, in' comparison with Fig. I, a refinement of structure. My invention centers in an expansible band 1 of rigid and sufiiciently resilient material, upon which gasoline has no deteriorating effect, expanded within, and by virtue of expansibility adjustable in its posi tion within, and when adjusted adapted by its expansibility to remain secured in' ime movable positionwithin the glass cylinder. The band extendsin horizontal plane around the vertically standingcylinder and accord-V ingly coincides with the line at which the tide of gasoline rising or falling within the tank meets the tank wall. The material preferably employed is hard rolled brass strip.

L The articular means preferably einployed or eitecting expansibility and com sequent adj ustability j of ithe band vertically within the cylinder are shown "in Figs III and IV. Thebandifs madesomewha't longer I I than the interior circumference of "the cylinder, theendsiar-e overlapped, and the iti-p of the 5 inner end is secured permanently or separably {to the web of the band, adjacent its opposite end. 'The-dra-wings show' aseparable anchorage, "consisting o'f a 'lugY'Q stamped and turned a from the web 01": the band, dipon' which the' notched' tip? of ,the

band at its opposite end bears.

The tip ofthe outer end of the band car'- ries a keeper 4- which engaging the inner end of the band adjacent its tip holds the inner end at that. point in close facefto face en gagement upon the outer end of the band,

but allows the innerend to slide longitudi-..

nally within the keeper.

By these means the overlapping ends of the band, between the anchorage 2 and thekeeper 4 may bow oppositely, as clearly shown in Fig. III. a j The outer end of the band carries at anlnterm-ediate point between lug 2' and'keeper 4 a threaded stem 5. ,This stem extends radially inward and through a slot 6 formed, 111 the band at a corresponding point adjacent its inner end. A nut 7 adjustable upon stem 5 completes the structure.

. It will be perceived that when the strip has been bent to circular shape, and its inner endthrust throughkeeper 4e and then interlocked with lag 2, the band may be reduced in diameter by sliding the, inner end within. keeper 4 and so increasing the downward bowing of the inner'end away from the up} ward bow of the outerend (Fig. III) and the band may be increased in diameter by sliding the inner end oppositely and so re I ducing the downward bowing ofthe lower end. Andit will further be perceive'd'that, the band having been jsufiicientlyreduced in diameter and the parts being then :in the position shown in Fig. III, theband maybe accurately placed within the cylinder and then by the turning of nut 7 be expanded and so brought to and secured. permanently. in position upon der.

' The band is necessarily of appreciable width, and a narrower strip for sighting purposes, with unobstructed [vision above and below, may be had by the expedient the inner wall of the cylin- .7

shown in Fig, The band is widened for a relatively short interval, and within such widened portion an eye is cut witha narrow strip 8 extending across the eye. The band manifestly maybe marked with legible indicia of quantity or fwith other" characters.

I claim as my invention:

1. An indicator for a cylindricalglasswa-lled container consisting of a band of rigid material adapted to be coiledwithin the J cylinder with ends overlapping, and ineans engaging the overlapped ends tending tov expand the coil and to hold the coiled band to engagen'ient' upon the cylinder. wall.

cent the opposite ends ofthe band with the intervening portions spaced apart, such means allowing engaged portions of the band to slide one upon another, and means for collapsing the spaced apart overlapping ends. j H

1 3. An indicator for a cylindrical glassrwalled' container consisting of a band of rigid. material adapted to be coiled within the cylinder, said band being provided adjacent one end with a keeper, the band atits opposite end extending through said keeper and slidablyengaged thereby,;and at'its tip secured to the web oft-he band adjacent the keeper-provided end, and means for reducing'the'divergenoe of theoverlapped ends between the keeper and the point of securing.

In testimony whereof I lia'vehereunto set my hand.
